Android- ANR Input dispatching timed out

Question

Im having this ANR on android 11. I was unable to find any proper solution for this even through its really complicated Stack trace to understand. Any Help will be appreciated.

Stack Trace:

Answer 1

Looking at your stack trace, lines containing com.google.android.gms.policy_ads seem to indicate that this is related to AdMob.

Looking at AdMob's support Google Group, there are a lot of complaints related to similar ANR's, just an example: https://groups.google.com/g/google-admob-ads-sdk/c/rCZMplesYEc

Given that this is in an external SDK we as dev don't have much control over, I think the main course of action is to reach out to AdMob's support with issues like this.

Answer 2

I've had this same issue happen on apps, and the stack trace points to an issue with Google AdMob SDK, and particularly dealing with WebViews when showing ads.
